I‘m currently playing the 3rd Movement of Moonlight Sonata and noticed myself always hitting the last note in Measure 22 (f##) even though it is a tied note. I never thought about not playing it, because every performer I have seen/heard playing this piece always played this note as well. Thus my ears were used to hear it and so I automatically played it without thinking. Now the question is, how am I supposed to know when to play the tie, and when to actually play the note, even though the notation tells me not to do it.
There is actually an indication in Measure 23 which tells me to use the thumb to play the g#, therefore one could conclude, that the note has to be played even though it is tied. Any ideas on this? Or am I missing something here?It’s the slow melody passage at 0:27
